¶ How do sub-accounts work?
Eternl wallet supports sub-accounts. This allows dividing a single wallet into different sub-accounts. This comes in handy if you would like to divide your wallet balance into different chunks. For example, if you want to delegate those different chunks to different staking pools.
If you have created a new wallet out of Eternl, you can choose the number of sub-accounts in the creation process. But you can also add sub-accounts to an existing wallet.
Sub-accounts are created in order, which means that Eternl will always create the same accounts, as will all other wallet apps. You will not lose any funds adding accounts.
You can see a list of all sub-accounts by clicking on the Account List Tab in the Account section of your current active wallet.
In this Tab, you can also add new sub-accounts to your current wallet:

- Verify on Ledger Live or Trezor Suite
¶ 5. Are there any other apps that could still be connecting to the device?

¶ What is a collateral?
A collateral (UTxO) is required when interacting with smart contracts. It is sent into smart contract transactions as a special input and acts as a kind of security.
These are usually around 5-10 Ada.
If all goes well, it will not be touched. If the contract “misbehaves”, it is confiscated and given to the stake pools impaired by that misbehavior.
Misbehavior means that the transaction shouldn’t have been allowed in the first place, because it fails validation. The DApps should not construct such transactions.
If there will be no interaction with a DEX, the feature could be turned off.
Further details are here: collateral-mechanism
¶ My collateral seems to keep disappearing, why?
When using Eternl.io combined with other wallets on the same seed, creating a transaction might cause the other wallet to consume the collateral UTxO.
There currently is no standard for setting collateral, and other wallets do not know the difference between a normal ADA UTxO and Eternl.io’s collateral UTxO.
Alternatively, a failed smart contract might’ve consumed the collateral UTxO (which is supposed to happen if one fails), to return your funds to you).

¶ What does locking UTxOs do?
It prevents those UTxO from beeing used for sending transactions and from beeing reported to DApps when asking for the wallets balance.
You can lock UTxOs manually:
Main menu > Account > UTxO list
click on the padlock icon to lock/unlock an UTxO
